2.控制器(Action)的核心代码
//导入用户列表
public String importExcel(){
//获取excel文件
if(userExcel != null){
//是否为excel
if(userExcelFileName.matches("^.+\\.(?i)((xls)|(xlsx))$")){
//导入
userService.importExcel(userExcel,userExcelFileName);
}
}
return "list";
}
3.逻辑处理（service）部分代码
@Override
public void importExcel(File userExcel, String userExcelFileName) {
try {
FileInputStream fileInputStream = new FileInputStream(userExcel);
boolean is03Excel = userExcelFileName.matches("^.+\\.(?i)(xls)$");
//1.读取工作簿
Workbook workbook = is03Excel ? new HSSFWorkbook(fileInputStream) : new XSSFWorkbook(fileInputStream);
//2.读取工作表
Sheet sheet = workbook.getSheetAt(0);
//3.读取行
if(sheet.getPhysicalNumberOfRows() > 2){
User user = null;
for(int i =2;i<sheet.getPhysicalNumberOfRows();i++){
//4.读取单元格
Row row = sheet.getRow(i);
user = new User();
//用户名
Cell cell1 = row.getCell(0);
user.setName(cell1.getStringCellValue());
//账号
Cell cell2 = row.getCell(1);
user.setAccount(cell2.getStringCellValue());
//所属部门
Cell cell3 = row.getCell(2);
user.setDept(cell3.getStringCellValue());
//性别
Cell cell4 = row.getCell(3);
user.setGender(cell4.getStringCellValue().equals("男"));
//手机号
String mobile = "";
Cell cell5 = row.getCell(4);
try {
mobile = cell5.getStringCellValue();
} catch (Exception e) {
double dMobile = cell5.getNumericCellValue();
mobile= BigDecimal.valueOf(dMobile).toString();
}
user.setMobile(mobile);
//电子邮箱
Cell cell6 = row.getCell(5);
user.setEmail(cell6.getStringCellValue());
//生日
Cell cell7 = row.getCell(6);
if (cell7.getDateCellValue() != null) {
user.setBirthday(cell7.getDateCellValue());
}
//默认用户密码
user.setPassword("123456");
//默认用户状态为有效
user.setState(user.USER_STATE_VALID);
//保存用户
save(user);
}
}
workbook.close();
fileInputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
4.上一个导出的例子没有贴出struts2的跳转配置，这个贴出来
